Packet Processing Method, Network Device, and Related Device

2. The method according to claim 1, wherein the step of separating separates the data of the application from the packet based on a delimitation template, wherein the delimitation template defines a rule of separation between the data of the application and other data in the packet.

3. The method according to claim 2, wherein the application is a TCP application.

4. The method according to claim 3, wherein the rule of separation defined in the delimitation template is: the metadata of the TCP application uniformly ends with a particular delimiter.

5. The method according to claim 3, wherein the rule of separation defined in the delimitation template is: a length of the metadata of the TCP application is uniform L1, and a length of the packet header of the packet is fixed.

9. The network device according to claim 8, wherein the processor is configured to separate the data of the application from the packet based on a delimitation template, wherein the delimitation template defines a rule of separation between the data of the application and other data in the packet.

10. The network device according to claim 9, wherein the application is a Transmission Control Protocol (TCP) application.

11. The network device according to claim 10, wherein the rule of separation defined in the delimitation template is: the metadata of the TCP application uniformly ends with a particular delimiter.

12. The network device according to claim 10, wherein the rule of separation defined in the delimitation template is: a length of the metadata of the TCP application is uniform L1, and a length of the packet header of the packet is fixed.

13. The network device according to claim 8, wherein the processor is configured to receive the packet of the application running in the server by aggregating a plurality of sub-packets belonging to a same data stream into the packet, wherein source internet protocol (IP) addresses and destination IP addresses of the plurality of sub-packets belonging to the same data stream are the same.
